The distance between rear part of posterior semicircular canal andanterior margin of the sigmoid sinus increased by 4.45 mm(57.8%),exposure areas ofposterior fossa dura increased by 157.32 mm~2 (64.3%)and operative angle of visionwas 329.6% that of retrolabyrinthine approach when performing PLPA approachcompared with retrolabyrinthine approach.

PLPA入路与迷路后入路相比，半规管后端与乙状窦前缘的距离较迷路后入路增加了4.45 mm (57.8%)，后颅窝硬膜的暴露面积增加了157.32 mm~2 (64.3%)，手术视角为迷路后入路的329.6%。

There was no significant difference between the length of the tentorial edge exposed via subtemporal keyhole approach and traditional subtemporal approach.

量化研究显示颞下锁孔入路中小脑幕缘显露长度与传统颞下入路无显著差异；脑干腹侧面显露长度与去颧弓颞下入路无显著差异，但大于保留颧弓颞下入路中的显露长度（p ＜0.05）。

Methods: Fifteen (30 sides) formalin-preserved human skulls were subjected to microsurgical dissection to evaluate the exposure scopes of 3 different endoscopic surgery approaches: endonasal middle meatal transpalatine approach, endonasal middle meatal transantral approach, and endonasal inferior turbinectomy transantral approach.

用手术显微镜对15具成人头颅标本按照鼻内镜下中鼻道经腭进路，中鼻道经上颌窦进路和中鼻甲切除进路要求进行显微解剖，观察不同手术进路暴露翼腭窝的范围。

Through the analysis of the conditions and therapeutic effects of 60 cases of the disease, we considered that urethral retention- catheterization and ureteric reflux are the main causes for urinary tract infection,and defense hypofunction of the host is a condition causing the infection.

通过对60例截瘫患者尿路感染病情及疗效分析，我们认为：保留导尿、输尿管返流是诱发尿路感染的最主要原因，宿主的防御功能低下是构成尿路感染的条件；在病程的不同阶段尿路感染各有特点；减少这一并发症的关键在于预防；采用中西医结合疗法能明显提高疗效。

This paper analyzes the key ideas of Minimum InterferenceRouting Algorithm for LSP routing and then surveys the current improved schemes of MIRA. According totheir technical methods, they are classified as reconfirming critical links class, utilizing traffic profile informationclass, adding admission control class, and solving multiple Quality of Service constraints class.

深入剖析了LSP选路算法中的最小干扰选路算法(minimum interference routing algorithm，简称MIRA)的关键思想，综述了对MIRA的各种改进方案，并依据其实现方案将现有主要最小干扰选路算法分为4类：关键链路的重新定位类、利用流量特征信息类、增加准入控制类和解决多服务质量受限类。

This invention discloses a duplexer and a multiplexer of the communication system and a method to realize them on a PCB circuit, which applies a 3db bridge and a low pass filter to constitute a hopstreet duplexer without waste band channels, in which, the signals are shunted and combined by the design of the circuit structure and power distribution of the 3-db bridge and phase offset function, the band filter of the low pass filter and the reflection function of a stopband to make up of a costless duplexer in theory to merge the two channels of different frequencies and reduce loss to increase volume and working bandwidth, then a multiplexer is formed by cascading multiple duplexers.

本发明涉及通信设备，公开了一种通信系统双工器和多工器以及双工多工方法，使得双工器和多工器能够在PCB电路上实现，并且体积小、损耗小、成本低、容量大。本发明中，采用三分贝电桥、低通滤波器构成无损耗频带信道合路的双工器，其中通过电路结构的设计并利用三分贝电桥的功率分配和相位偏移功能将各路信号进行分路和组合，利用低通滤波器的频带滤波和阻带反射功能联合三分贝电桥构造一个理论无耗的双工器，使两路不同频率的信道合路，降低的损耗、提高容量和工作带宽。通过多个上述双工器的级联构成多工器。

He has chosen a path It's the right path.It's a path made of principle that leads to character.let him continue on his jourey,You hoke this boy's future in your hands, committee,It's a valuable future,believe me.Don't destroy it .

轮到查理了，他也在一个人生的十字路口，他必须选择一条路，一条正确的路，一条有原则的路，一条成全他人格的路，让他沿着这条是继续前行，这孩子的前途掌握在你们的手里委员们，他会前途无量的，相信我，别毁了他！

From the River Plate in the south and with the approach of the plate to the point of view: in its region at the junction of the small business sector for the West, to West River Road, the road to the east, as it is in the middle of the woolen mill where the region Barrier, so people tend to choose the way the East is relatively good support to the plate, the regional prices and slightly higher than the recognition River.

从清河板块和与其南部临近的上地板块来看：以其交界区域的小营西路为界，路西为清河，路东为上地，由于现在位于中间的毛纺厂所在区域的阻隔，所以人们比较倾向于选择路东配套相对比较好的上地板块，这一区域价格和认可度略高于清河。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
